HEELING-MACHINE.

M. PETTEN- residing at Haverhill, in the county of Essex and vwhile theattaching or tion, and, .with

State of Massachusetts, have invented'an Improvement invlleeling-Machines, of which the following is a specification.

This invention relate to certain iinprovements in heeling machines, andmore particularly to lieeling machines o type shown and described in myPatent #1,119,763, dated Dec. 1,1914, in which one heel is pricked byawls on an awl-block, which is connected to the 4cross-head, while thetop lift is being spanked onto another heel which has just been attachedtothe shoe, and the awl-block 'is sustained,in operative, independentlylof the cross-head,

nail-driving operation is being performed. Inthe machine disclosed in mysaid prior patent, frictional devices were employed for sustaining theawl-block during the nail driving operathis. frictional y engagingmeans, it has ibeen found'y that, under some conditions, the jar of themachine which occurs at the time the clown-stroke is finished, causesthe awl-block to becomeldi'sengaged from its support, so that it fallsuntil the awls strike the nail-plate slide, which, at that time, isdirectly therebeneath, thereby causing the awls vto'become chilled orbroken.

move into engagementwith the awl block whenever the nail-plate is movedforward beyond the pricking position and which will be caused to remainin this position until the nail-plate is again retracted.v

For a more complete understanding of my invention reference is made tothe accompanying drawings, in which, Y

Figure 1 is a front elevation of the crosshead of the machine partsthereof. Fig.

` Fig. 3 'is a cross-sectional view taken on the Specification ofLetters Patent.

f the so that the awl-block can not possibly `become disconnected fromthe parts which support it, and the awls are illustrating certain 2 is aplan view thereof.

line 3-3 of Fig. 1. Fig. 4 is ay detail view of a portion of theoperatingmechanism.

Inasmuch vas a `complete description of the entire machine may be foundin said prior application, only thoseV parts have been shown r whichnecessarily coperate withI the particular invention to which thisyapplication relates.l

As shown in the drawing, G has theturret 7 ymounted in the head in theusual manner. yThe nail-plate; 17 is mountedl in guideways in thenail-plateholder M, and is adapted vto be` moved Vto nailingpositionover vtliejack, orinto pricking position over the .heel-holder, disposeddirectly inthe rear thereof, (neitlierbeing shown): The fawl-carrier Q8is slidably mounted `between th cross-head and is adaptedto belocked-,tothe latterfby the locking shaft 51, which is moved` intojand out of'locking position upon rotation of the turret y In said priory patentIfhave illustrateda safety mechanism for ,tlief. turret which preventsthelnail-plate from being'movedinto nailing vposition Aover :the jackwhen the turret is Yin spankingposition, `and also preveiitsithe turretfrom being"movedfrom nailing position into spanking positionwheii theslide is in nailing positiony Overthe jack, `This mechanismisiilustrated lin the present drawings, cally disposed rod 14: yat itslower end, and having an arm 85 secured thereto, which is arranged to beengaged and swung aside `by the nail-plate slide 17 when the llatterfismoved forwardv beyond the pricking ,position and a finger 86' is splinedon'said shaft and is arranged to engageanotch in the turret yto lock thesame. In the particular embodiment of my invention' shown, I employ thissafety mechanism ,in performing the additional function oflockingthe'awlcarrier in raised position during the drivingoperation of ythecross-head.'y To accomplishthis result the rod 84C is extended upwardabovel the upper end ofthecross-head, and a finger 110 is secured vonsaidextended upper end.,

sion 28 ywhich has-a lateral projection",Qfl

being so arranged that, in

projection 28V and comprises averti- Stmounted on the holder,v

,The v awl carrier 28 is provided with an eXten` the 'Cmsshead holder laand the,

said linger will beheld directly beneath said projection and willsustain the awl-carrier in its raised position. The relative position ofsaid linger 110 and said arm 85 is suchl that, when the arm 85 is swungforward by the nail-plate slide, as the latter is moved forward beyondthe front end of holder 14, so that the linger 86 locks the turret, thelinger 110 will be swung beneath the projection 28, .so that it willlock the awl carrier in raised position, as shown in F ig. l.

To describe the operation more completely, when the cross-head movesupwardly, after the pricking operation is linished, the pin 100 thereinengages the awlcarrier 28 and lifts it to its highest position, as shownin Fig. 3. The nail-plate slide is then pushed forward and swings thelinger 110 beneath the projection 28, as before described. The shaft'84will remain in this position, holding the linger 110 beneath saidprojection while the nailing-operation is performed, so that, when thecross head moves down to` perform the nailing operation, the awl carrierwillbe sustained in its raised position during the entirenailingvoperation, and will not be permitted to fall so that the awlswill strike the nailplate slide, When the nailing operation has beenfinished and the nail-plate is drawn back to pricking position,thespring 88 will rotate the shaft 84, and will move the finger 110 frombeneath the projection 28, so that the awl carrier will no longer belocked in raised position, and, when the turret is rotated into spankingposition, the locking bolt 51 will be moved into engagement with thecarrier 28, so that the pricking operation will be performed on the nextmovement'of the cross-head.

I claim: l l. In a heeling machine of the character described, avertically movable head, a nail plate, movable beneath said head betweenriving and pricking positions, a vertically movable awl carrier disposedadjacent said head, means to connect and disconnect said head and saidcarrier, a locking device supported independently of said head andmovable between positions to lock said awl carrier'in raised positionand to unlock it to permit it to move downwardly with the head, means,actuated on movement of the nail plate to driving position, to move saidlocking device into locking position, and means to return said lockingdevice to unlocking position when the nail plate is moved into prickingposition.
